仅限FireFox中的文件下载问题 [英] File Download issue in FireFox only

问题描述

我已经建立了一个消息传递系统，用户可以在其中相互发送消息，也可以在消息中作为附件发送文件(类似于简单的电子邮件系统).如果文件名包含空格(例如，ticket.doc的602_Sign文件)，则我在Firefox中遇到问题在Firefox中，它将保存为602_Sign.doc，但是它应该显示完整的名称，问题在IE和chrome上运行正常，下面是我下载文件的代码

I have make a messaging system in which user can send messages to each other, they can also send files as attachement in message(its like simple email system). I am facing an issue in firefox, if file name contains space(eg 602_Sign File for ticket.doc) in firefox it'll save with 602_Sign.doc however it should display complete name,issue is working fine on IE and chrome,below is my code for downloading file

public ActionResult Download(string attFileName)
        {
            string FileName = Path.Combine(Server.MapPath("~/MessageAttachmentFiles"), attFileName);
            System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
            response.ClearContent();
            response.Clear();
            Response.AddHeader("Content-Disposition", string.Format("attachment; filename = {0}", System.IO.Path.GetFileName(FileName)));
            response.TransmitFile(FileName);
            response.Flush();
            response.End();
            return null;

        }

推荐答案

以下内容应该有效

response.AddHeader("Content-Disposition", 
                    string.Format("attachment; filename = \"{0}\"",
                    System.IO.Path.GetFileName(FileName)));
